RAILWAY-FROG.

SPECIFICATION forming part of Letters Patent No. 682,863, dated Septemberl'?, 1901.

Application filed April 2, 1901- Serial No. 54,026. (No model.)

T0 @ZZ whom t may concern:

Be it known that I, DAVID F. VAUGHAN, a citizen of the United States, residing at Haddontield, Camden county, State of New Jersey, have invented certain new and useful Improvements in Railway-Frogs, lof which the following is a full, clear, and exact description, reference being had to the accompanying drawings, of which- Figure lis a plan View of a railway-frog in Fig. 2 is a section on line ac, Fig. 1. Fig. 3 is a plan view of the filling-piece and supplemental wing-rails detached. Fig. Llis a similar view of a modification of the iilling piece, in which the frog point, as also the supplemental wing-rails, are integral with said piece. Fig. 5 is a section similar to Fig. 2, but in which the said modioation is substituted for the form shown in Figs. 1, 2, and 3. Fig. 6 is a section similar to Fig. 2, but in which the supplemental wing-rails are made separate from the iilling-piece. Fig. 7 is a plan view of the said supplemental wing-rails detached.

The object of this invention is to provide a railway-frog capable of withstanding the wear and tear usually resulting from the passage over the open throat or flangeway of the frog of the locomotive and car Wheels.

The leading feature of the invention relates to what I shall term supplemental wingrails of hard or hardened metal secured along the inner sides of the usual wing-rails adjacent tothe sides of the point of the frog, the said supplemental rails forming a bearing for the car-wheels and their inner sides forming, with the sides of the point of the frog, the usual iiangeway or throat, whereby certain advantages are obtained, as hereinafter mentioned.

In carrying out my invention, reference being had first to Figs. 1, 2, and 3 of the accompanying drawings, I form the point 1 of the frog by the converging track-rails 2 3 in the usual way, made of the ordinary style or pattern of rail; but instead of bending the wing-rails 4 so thatv their inner sides will forml part or all of the channel or iiangeway and bending their free ends outwardly to form a wide entrance, as is usually done, I bend said rails outwardly in advance of the frog-point to an unusual extent, thus making a throat or space between the rail and the point of abnormal width, which space extends from the toe of the point to the free end of the outwardly-bent portion of the rails and which is reduced to the usual width by the supplemental wing-rails shortly to be described, as seen in Fig. 1.

5 is a block or plate, which l shall term the filling-piece, that is tapered to correspond with the taper of the wing-rails 4 and whose sides are adapted to fit against the webs of the wing-rails, respectively, and against the under side of the heads of the railsY and the upper side of the Iianges or feet of the rails, as seen in Fig. 3. This fllling-pieceextends past the point of the frog a suitable distance in both directions. It has a longitudinal slot 6 at its wider end, adapted to receive the webs of the converging track-rails 2 3, while lthe point 1 extends over and rests upon the filling piece. Rising from the top of the piece, adjacent to the sides thereof, are what I have termed the supplemental wing-rails 7, whose upper surfaces are substantially even with those of the wing-rails, as seen in Fig. 2. The inner sides of these supplemental wing-rails are substantially parallel with the sides, respectively, of the point and of the said track-rails 2 3, forming the usual tlangeway 8, as shown. The width, outside to outside of said supplemental wing-rails at the widest end is substantially equal to the width between the heads of the wing-rails 4:; but the width increases relatively toward the narrow end, and the inner side of each of the wing-rails 4 is correspondingly cut away or planed oft to let in that part of the supplemental vwing-rails, the object being to have the inner sides of the end portion of the lat-V terin front of the point in line with the side of that part of the Wing-rails and at the same time to have the necessary width or body to the metal at that place. The supplemental Wing-rails are bent or curved outwardly at 9, as shown, in order to provide a wide flangeway at that end to insure a safe entrance of the ilanges of car-wheels. Imake the filling piece or block 5 of hardened steel or other suitable hard metal or the supplemental wing-rails only may be hardened, the object being to have a material that will withstand the shocks and wear and tear incident to IOO heavy traffic where the wheels of cars cross the open fiangeway of 'the frog. Thevparts are assembled as seen in Figs. l and 2, being secured together by means of through-bolts l0.

It will be obvious that the wheels of cars passing in either direction across the open angeway adjacent to the point of the frog will bear upon one ofthe supplemental Wingrails, also the wheel fianges entering the flangeway between the' latter and the frogpoint.

I sometimes make the point l integral with the filling-piece, as illustrated in Figs. 4 and 5, in which case the pointed end of the trackrail 2 will be correspondingly cut oif, so that when entered in the slot 6, as before mentioned, the end thereof will be iiush with the contiguous end of the point.

The form of the device shown in Figs. 6 and 7 differs from the form shown in Figs. l, 2, and 3 only in that the supplemental wingrails instead of being an integral part of the filling-piece are made separate and bolted together with the other parts.

I do not claim to be the first to use in a railway-frog a block or section of hard or hardened metal secured to the side of a wing-rail and adapted to form a durable bearing for the wheels of cars passing over the frog; but my construction hereinbefore described enables me to produce a frog of the kind mentioned which may be more readily and cheaply made than any other with which I am acquainted. It also obviates the necessity of cutting away and thus weakening the footilanges of the wing-rails or of the point-forming rails and also the bending outwardly of the free end of the wing-rails to form the wide entrance to the iiangeway.

My invention is applicable to that kind of railway-frog in which one of the wing-rails is fixed and the other laterally movable. In such frog the supplemental wing-rail would be used only in connection with the ixed wing-rail.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination in a railway-frog, of the point, the wing-rail bent outwardly in advance of said point to an abnormal extent, to form a space of abnormal width between the side of said rail and the side of the point, said space extending from the toe of the point to the free end of the outwardly-bentportion of the rail, the filling-piece, the hard-metal supplemental wing-rail secured to said lillingpiece and fitted to the side of the head of said wing-rail, and having its inner side substantially parallel with the side of the point, and forming, with the latter, the angeway, substantially as and for the purpose set forth.

2.

3. The combination in a railway-frog, of the point, the wing-rail, bent outwardly in advance of said point to an abnormal extent1 to form a space of abnormal width between the side of said rail and the side 4of the point, said space extending from the toe of the point to the free end of the-outwardlybent portion of the rail, the filling-piece, the hard-metal supplemental wing-rail fitted to the side of the head of said wing-rail, and having its inner side parallel with the side of said point, and having also its wider end bent or curved outwardly toward said wingrail, and separated from the said point to form the flangeway, as and for the purpose set forth.

5. In arailway-frog, the combination 'of the point, the Wing-rail bent outwardly in ad vance of the said point to an abnormal extent, to form a space of abnormal width between the side of said rail and the side of the point, which space increases gradually in width from the toe of the point to the free end of the outwardly-bent portion of the rail, the iilling-piece, the hard-metal supplemental wing-rail secured to said filling-piece Aand fitted to the side of the head of said wingrail, and having its inner side substantially parallel with the side of the point, and forining, with the latter, the ilangeway, substantially as and for the purpose set forth.
